New DK Tank

I'm starting up a dk here in the coming week and plan on running it as a tank for dungeons and was wondering if any of the tanks here in guild could point me in the right direction for general tank game play tips and possibly up to date tank builds  with what armor sets and the like that people are using. Everything I keep finding is more for pvp or from before/around when IC dropped.

Reach out to MIKLOPZ, good tank,  usually willing to help

When is he normally on... work nights with a weird schedule 

Usually mornings
